Developed and tested various C++/Python OOP features for NVIDIA Omniverse Isaac Sim robotic simulation platform. • Discovered then bugfixed C++ sensor data persisting in buffers on restart of simulation and added absolute orientation quaternion output for IMU sensor. Also updated pybind Python interface. • Used OmniGraph Python API to create drag-and-drop graph nodes that acquire and forward sim data from IMU and Contact sensors. • Devised pytest tests to verify accel/gyro/orientation and contact sensor corner cases using sample robots. • Unit tested differential base robot assets to expose odd caster wheel behavior and attempted fixes. • Authored an instructional tutorial for the Read IMU OmniGraph Node and verified in collaboration with QA.

Fall 2021:Research assistant collaborating on vision path planning project for robots in unknown, structured environments:• Devised graph-node based path-planning algorithm for sensor maps generated by robot simulated in ROS Gazebo. • Developed OpenCV C++ script that overlays floorplans with Voronoi skeleton and returns key points as nodes. Spring 2021: • Collaborated on search and rescue environment in Unreal Engine to evaluate human trust of robot AI agent.• Setup backend Unreal sim communication to MySQL database using Unreal Blueprint coding, and PHP.

Clarksburg, Maryland, United States

Summer Intern involved with development and testing of platforms.• Developed a robust embedded Linux platform for forwarding GNSS corrections from reference network/base station to receiving Olli AV via MQTT over 4G-LTE cell network. o Programmed + cross-compiled C/C++ apps for capturing and forwarding data to navigation unit. o Got GPS position std dev down to ~1 cm with base station corrections. • Captured and parsed TI mmWave Radar distance and speed data using Wireshark and Octave.

Collaborating on DARPA Artificial Social Intelligence for Successful Teams (ASIST) as part of the Cornell University research team. • Wrote scripts in Python (numpy, pandas), to parse player data visualized using Matplotlib• Worked with Docker and MQTT communication in the testbed implementation. • Collected gameplay data from several of test participants.Microsoft Malmo Minecraft is used as a platform to collect user play data from a search and rescue mission. This goal is to develop an AI theory of mind (ToM) model that effectively responds and works with human players.
